ezp2010

[dj_ricoh]

Hello Badcaps techs!
i come with a stupid problem.
Not a big problem but its unknown for me.

So let me begin.
Yesterday i had a Hp 15 with no power nothing, no led , 0.

I desolder the bios read it and try to write it back. Nothing.

the ezp2010 can read every chip over 1mb but it can`t delete it.
2mb 4mb 8mb etc. it reads the chip but it can`t delete.

i`m installing on another notebook the device so i can take some picture and show you.
the 1MB chip tough it can read it delete it and write it back.

i do know the bios chips that i took down to test may be faulty but for frak sake i tested like 5 chips. i had 1 from a dv9000 with 1mb and it was ok because the board was massacre on bga chips.

the Question is did you had any problem like this? to delete and verify it came back the data(its like it was not deleted).

i`ll make some picture soon so i can show you.

the time tough for deleting a chip its almost equal like writing.

but with mine now its not even 1 sec(even lower) its like its doing a quick format not full format on a drive.

Re: ezp2010

It looks like the chip is locked like those from HP with Bios and ME section etc.
They are also ignoring the write cycle. Does the programmer not come back with a error?

Re: ezp2010

get datasheets.
i'm not sure about serial flash, but a lot of parallel flash you can lock the sectors.
to unlock them you send unlock command or you put high voltage on one of the pins while erasing / writing.
so maybe serial flash supports sector locks?

Re: ezp2010

i need to find a few good boards with bios chip over 1mb to confirm and see if it does the same.

2 weeks ago i reflash a hp 15 and a hp 17 and everything was ok.

i need to check the wires on the adapter because i had only problems from the first minute

ty btw for the reply

Re: ezp2010

Try to update the firmware of ezp2010

clean the socket pins for good contact

hope it will help

Re: ezp2010

so yes! all of he chips i had where dudu!

starting from TV satellite boxes, dell M series, some hp g6 series.

every single one i thing they are dead(can`t be delete) except for the dv9000 bios that work.

today i manage to fix a hp envy m6 and after i finish finding the short i took down the bios just to test the ezp2010 and the bios chip its 4mb and it work normally .

so i`m sorry for the trouble and maybe this will be a lesson for me about the bios chip even if its tv box LOL.

i need a new stash of chips

Re: ezp2010

That was a really bad run of chips

Re: ezp2010

post some part numbers please.

Re: ezp2010

those are all the chips i tested saturday and it made me think that the ezp its broken.

i can`t remember witch one its from where because it put them on a box.

i need to start recovering again a new stash of chips.

i got a lot of boards tough and i need other components to, but it takes alot of time to take them of, clean them and test them and label theeeeeeeeeeem.
omg i feel sick only when i`m thinking

Re: ezp2010

did you use soic8 adapter? might be that was broken, and the programmer still good. try other soic8 adapter first

Re: ezp2010

I tested last night with a 4mb bios from envy m6 and it was ok

Maybe i was lucky with my soare stash of bios chips.

Bad luck maybe? And maybe thats why the boards ended up for spares.

Should have made some pics of the boards to see some pro techs(from london) what they did with those boards.

Re: ezp2010

reading some datasheets, it's probably what i said.

look at page 11.
sector based "read only" protection mode.

Re: ezp2010

wow.
i`m such a fool with a big illusion that i'm progressing

Re: ezp2010

your programmer probably has an option to set or clear those bits.

Re: ezp2010

The true benefit of our mistakes is that they make us progress!!!

I do believe in bad luck… but it makes much more sense to me you came across a serious bug with the ezp2010 software not being able to cope with WREN command (and probably AAI too)!

Btw, why are u still using ezp2010?
Spend less than 4€ and buy a ezp2014 chinese clone (without any fancy(?) box), aka 2014 Best Blackstone Tyrant Gold.
Main advantage: updated software and database [2014.10.18]

Re: ezp2010

got a link for that?

[megaraider]

Re: ezp2010

got a link for that?

You can find it described here along with the link to the software.

You can buy it on eBay, here for example.

The software file is 391MB mainly because it comes along with too many firmware files for obsolete devices.
Deleting all that garbage reduces compressed file size to less than 3MB.
If having trouble pm me for the software.

Re: ezp2010

oh the ch341
have you got cracked software that does not need the reg key?
or just the older v1.18 and under?

Re: ezp2010
